Wozniacki, who had actually lost two of her three previous meetings with Zheng, got broken in the sixth game of the match and couldn't recover, losing a lengthy 56-minute set, 6-3, then calling it quits in the pair's fourth meeting.

"I knew she had a problem with her ankle yesterday. My coach told me I should forget about it, though, and just concentrate on myself," Zheng said. "I feel lucky to make the semifinals here, but I wish we could have finished our match today."

Earlier in the day, Li Na - at No.3 now the highest seed remaining in the Premier-level tournament - breezed past Sara Errani, 6-2, 6-1.

"I just played her in Stuttgart, but my coach told me this morning the court here is very different from there," Li said about her win over the feisty Italian. "I just had to concentrate on every point and I did that. I played consistently."

After becoming China's first Top 10 player earlier this year, Li had somewhat of a slump, including a four-match losing streak between Dubai and Miami - but she has found her feet again on clay courts, reaching the quarters at Stuttgart and Madrid and the semis here. She is one of the form players going into Paris.

"After Miami I went back to my home and took a 10 day break - 10 days without tennis," Li said. "After that I felt ready for tennis again. I went to Munich and started training very hard. I'm glad to see the hard work has paid off so far."
